Rules for Dining with Astronauts

From NASA's Letters to Earth, a guide to "How to Be Civilized on the Space Frontier." Below, advice on entertaining while in orbit from astronaut Don Pettit:

Do not bring drinks.

Now is the time to break out those thermal-stabilized pouches of beef steak that you have been hoarding. Bring out any specialty item from your personal crew allotment (these items arrive on the periodic unmanned resupply spacecraft that visit us). Perhaps you can share a can of smoked anchovies, New Mexico green chili, or a piece of Old Amsterdam cheese. Always serve something special that is not repeatedly eaten on the standard nine-day menu. Being generous now will reap more benefits than eating these delicacies in solitude.

...You can provide a special treat if you have access to one of the research refrigerators. In space, all your food is either hot or at room temperature. When you live in an isothermal environment, it can be a real treat to serve your guests a bag of cold water.
